Title: I.c. engine fuel injection system with a positive displacement pump dispensing a fixed amount of fuel
Inventor: ALLEN JEFFREY
IPC: F02M59/36
Filed: 2005-08-05
Abstract: An i.c. engine has a variable volume combustion chamber 83, an air intake system 88, 91, an exhaust system 87 and a fuel injection system comprising a pump/injector 90, 96 which functions as a positive displacement pump and dispenses a fixed amount of fuel for each and every operation of the injector. The pump part 96 of the fuel injector comprises a housing 103 containing a fuel chamber 98 with respective inlet and outlet one-way valves 99, 100. A piston 102 is slideable in the chamber 98 and is spring-biassed into engagement with a camming surface to draw fuel into, and force fuel from, the chamber 98. The camming surface 93 may be provided on a wheel 94 that rotates with the crankshaft 85. An ECU 92 controls how many cam lobes (110, fig.3) of the camming surface 93 can cause injection of fuel by activating a solenoid 106 to displace a pintle 108 to prevent the inlet one-way valve 99 from closing. The ECU selects an appropriate number of pulses in response to engine load as sensed by the position of the throttle valve 91 and counts the number of injected pulses in an engine cycle before deactivating the inlet one-way valve 99. Alternatively, a mechanical linkage may be provided between the throttle 91 and the injector pump 96. The or each engine cylinder may be provided with two injectors 90 dispensing unequal amounts of fuel. The simple fuel injection system is suitable for small, low-power engines, eg for chain saws, lawn mowers, small generators, mopeds and scooters.

Title: High colour diamond production and usage
Inventor: WILLIAMS STEPHEN DAVID
IPC: C30B25/02
Filed: 2006-06-22
Abstract: A method of producing CVD diamond having a high colour (near colourless), which is suitable for optical and electrical applications in addition to as a gem stone. The method includes adding a gaseous source comprising a second impurity atom type to counter the detrimental effect on colour caused by the presence in the CVD synthesis atmosphere of a first impurity atom type. The first and second impurity atoms are different from one another and can be selected from nitrogen and atoms that are solid in their elemental state (e.g. silicon, boron, phosphorus or sulphur). The described method applies to the production of both single crystal diamond and polycrystalline diamond.

Title: Using a dither signal to minimize data-dependent power variations in a device
Inventor: MOORE GEORGE S
IPC: H03M1/06
Filed: 2007-09-13
Abstract: A system minimises data-dependent power fluctuations in a mixed-signal device, such as an ADC or DAC. The system includes summing an input signal 101 with a dither signal 202 produced by dither generator 201. Processing means 100, e.g. an interpolator or decimator, processes the summed signal 203. The effects of dither are substantially removed from output 204 by equivalently processing the dither signal 202 alone using duplicate or equivalent processing means 200. The processed dither signal 206 is subtracted from output 204 using summer 208, thereby cancelling components of the processed signal that result from the presence of the dither signal. Randomizing the input signal by summing it with dither signal 202 ensures that the power consumption of the device is essentially constant regardless of fluctuations in input signal. Unwanted variations in operating temperature in an ASIC are avoided. Non-linear operation of units 100, 200 is avoided by two's complement arithmetic or by constraining the amplitude of the dither signal with scalers (311, 312).

Abstract: Method for providing for cables 100 with secured terminations comprises providing a cable with inner tube 104 surrounding an optical fibre or fibres 102, removing a portion of the inner tube to expose a length of the optical fibre extending from an end of the inner tube, surrounding at least part of the exposed fibre adjacent the end of the inner tube with an elastomeric packing sleeve 106, positioning a retention tube overlapping outside both the inner tube and the elastomeric packing sleeve, securing the retention tube to the inner tube and deforming the retention tube in a radial inward direction where the packing sleeve is disposed in the retention tube to squeeze the packing sleeve into gripping engagement with the optical fibre. A further section of aluminium tubing 108 surrounds the inner tube, and armour tubing 110 surrounding the aluminium tube. The aluminium tube resists collapse of the inner tube at bends in the cable, inhibits or prevents hydrogen from reaching the fibre, and facilitates termination of the cable. For example, terminating the cable may include crimping (300) the armour tubing to deform the aluminium tube into gripping engagement with an outside of the inner tube and an inside of the armour tubing. In some embodiments, a retention assembly secures the fibre relative to the inner tube and includes a retention tube secured to the inner tube and a packing sleeve squeezed into gripping engagement with the fibre by radial inward deformation of the retention tube where the packing sleeve is disposed in the retention tube.
